Abstract

Die Wandung (4) eines Elektroofengefäßes ist von einer Tragkonstruktion umgeben, die aus parallel zur Drehachse des Gefäßes verlaufenden Trägern (8a bis 8h) besteht. Die Träger (8a bis 8h) verbinden den Rand (5) des Gefäßes, auf den der Gefäßdeckel auflegbar ist, mit dem Traggestell (2) des Gefäßbodens (3). Damit die Durchführung von Erneuerungsarbeiten an dem Gefäß bzw. Reparaturen, insbesondere bei Öfen, deren Gefäßwandung teilweise lediglich aus zusammengefügten, freiliegenden Kühlelementen (7) besteht, erleichtert wird, wurde vorgeschlagen, einen Teil der Träger (8a bis 8h) aus dem Bereich der Gefäßwandung (4) seitlich entfernbar auszuführen.The wall (4) of an electric furnace vessel is surrounded by a support structure which consists of supports (8a to 8h) running parallel to the axis of rotation of the vessel. The carriers (8a to 8h) connect the edge (5) of the vessel, on which the vessel lid can be placed, with the support frame (2) of the vessel bottom (3). In order to make it easier to carry out renovation work on the vessel or to carry out repairs, in particular in the case of ovens, the vessel wall of which in some cases only consists of assembled, exposed cooling elements (7), it was proposed to remove some of the supports (8a to 8h) from the area of the vessel wall (4) to be removed laterally.

Description

Die Erfindung betrifft ein Gefäß für einen Elektroofen, insbesondere für einen solchen Ofen, dessen Gefäßwandung ganz oder mindestens teilweise im oberhalb der Schmelzzone liegenden Bereich lediglich aus zusammengefügten, freiliegenden Kühlelementen besteht, mit einem oberen Rand, auf den der Gefäßdeckel auflegbar ist, wobei der Rand mit Hilfe von an der Außenseite der Gefäßwandung parallel zur Gefäß-Drehachse verlaufenden Trägern mit der Tragkonstruktion des Gefäßbodens verbunden ist.The invention relates to a vessel for an electric furnace, in particular for such an oven, the vessel wall of which consists entirely or at least partially in the region above the melting zone only of assembled, exposed cooling elements, with an upper edge on which the vessel lid can be placed, the edge is connected to the supporting structure of the bottom of the vessel with the aid of supports running on the outside of the vessel wall parallel to the axis of rotation of the vessel.

Ofengefäße für Metallschmelzöfen mit einer hitzebeständigen Wandung, die ganz oder mindestens deren Teile aus Kühlblöcken aufgebaut ist, sind zum Beispiel aus der DE-OS 27 45 622 und DE-OS 27 36 385 bekannt.Furnace vessels for metal melting furnaces with a heat-resistant wall which is made up entirely or at least of its parts from cooling blocks are known, for example, from DE-OS 27 45 622 and DE-OS 27 36 385.

Bei öfen dieser Art ist es notwendig, die die Gefäßwandung bildenden, zu Blöcken zusammengefügten Kühlelemente in regelmäßigen Zeitabständen zu ersetzen.In furnaces of this type, it is necessary to replace the cooling elements which form the vessel wall and are assembled into blocks at regular intervals.

Aber auch bei Elektroöfen mit Gefäßen üblicher Konstruktion, deren Wandung mit feuerfester Ausmauerung ausgekleidet ist, muß diese Auskleidung regelmäßig erneuert werden.But even with electric ovens with vessels of conventional construction, the walls of which are lined with refractory lining, this lining must be replaced regularly.

Bei den gegenwärtigen Konstruktionen der Elektroöfen ist der Ersatz der Gefäßwandung zeitaufwendig und teuer. Die Gefäßwandung ist nämlich von einer Tragkonstruktion umgeben, die im wesentlichen aus parallel zur Gefäß- Drehachse verlaufenden Trägern besteht (DE-OS 28 19 836 - Pos. 30; DE-OS 26 40 598 - Pos. 44, 46 und 48). Die Tragkonstruktion verhindert, daß die Erneuerungsarbeiten von außen durchgeführt werden können, vielmehr muß das Montagepersonal im Inneren des Gefäßes arbeiten.In current designs of electric ovens, replacement of the vessel wall is time consuming and expensive. The vessel wall is in fact surrounded by a support structure which consists essentially of carriers running parallel to the axis of rotation of the vessel (DE-OS 28 19 836 - item 30; DE-OS 26 40 598 - items 44, 46 and 48). The supporting structure prevents the renovation work from being carried out from the outside; rather, the assembly personnel must work inside the vessel.

Bei Arbeiten an der feuerfesten Auskleidung ist es in vielen Fällen günstiger, wenn das Gefäß für das Wartungspersonal das Gefäß von außen zugänglich ist. Vor allem können verschiedene Hilfsmechanismen besser eingesetzt werden, ferner muß der Ofen nicht so tief abgekühlt werden wie bei Innenarbeiten, und schließlich kann in bestimmten Fällen das ausgebaute Material günstig in Richtung nach außen hin entfernt werden.When working on the refractory lining, it is in many cases more advantageous if the vessel is accessible to the maintenance personnel from the outside. Above all, various auxiliary mechanisms can be used better, the furnace does not have to be cooled as deeply as when working inside, and finally, in certain cases, the removed material can be removed favorably towards the outside.

Aus der DE-OS 26 40 598 ist ein Verfahren zum Entfernen der Gefäßwandung aus einem elektrischen Lichtbogenofen bekannt, wobei die Tragkonstruktion mit Hilfe eines Kranes vom Ofen weg angehoben wird (Seite 17, Zeile 23 ff, Seite 18, 1. Absatz sowie Fig. 3). Dabei muß die Mantelkonstruktion von der Tragkonstruktion 12 des unteren Teiles gelöst werden; es ist einleuchtend, daß eine solche Arbeit sehr aufwendig ist und den Betrieb verteuert. Außerdem wird mit der ganzen schweren Mantelkonstruktion manipuliert, was bei manchmal gedrängten Raumverhältnissen in den Ofenhallen umständlich ist.From DE-OS 26 40 598 a method for removing the vessel wall from an electric arc furnace is known, the supporting structure being lifted away from the furnace with the aid of a crane (page 17, lines 23 ff, page 18, 1st paragraph and Fig. 3). The jacket structure must be detached from the support structure 12 of the lower part; it is obvious that such work is very complex and expensive to operate. In addition, the whole heavy jacket construction is manipulated, which is cumbersome when the space in the furnace halls is sometimes crowded.

Der Erfindung liegt die Aufgabe zugrunde, ein Gefäß der eingangs genannten Art zu schaffen, dessen Aufbau die Erneuerungsarbeiten an der Gefäßwandung erheblich erleichtert. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß ein Teil der Träger der Tragkonstruktion aus dem Bereich der Gefäßwandung seitlich entfernbar ist.The invention has for its object to provide a vessel of the type mentioned, the structure of which considerably facilitates the renovation work on the vessel wall. According to the invention, this object is achieved in that a part of the supports of the supporting structure can be removed laterally from the area of the vessel wall.

Nach einem weiteren Merkmal der Erfindung sind die entfernbaren Träger an einem Ende von der Gefäßwandung wegschwenkbar gelagert..According to a further feature of the invention, the removable supports are pivotally mounted at one end away from the vessel wall.

Vorteilhafterweise ist die Schwenkachse derartig angeordnet, daß sie tangential zur Gefäßwandung verläuft. Die Schwenkachse kann nach einem weiteren Merkmal der Erfindung an der Tragkonstruktion des Gefäßbodens vorgesehen sein.The pivot axis is advantageously arranged in such a way that it extends tangentially to the vessel wall. According to a further feature of the invention, the pivot axis can be provided on the support structure of the vessel bottom.

Nach einem weiteren Merkmal der Erfindung sind die entfernbaren Träger mit dem Gefäß durch Schrauben oder Keile verbunden.According to a further feature of the invention, the removable supports are connected to the vessel by screws or wedges.

Die Erfindung wird anhand eines Ausführungsbeispiels und der Figuren erläutert. Es zeigen:

  • Fig. 1 ein erfindungsgemäßes Gefäß eines kippbaren Lichtbogenofens im Axialschnitt,
  • Fig. 2 eine Draufsicht des Ofens gemäß Fig. 1.
The invention is explained using an exemplary embodiment and the figures. Show it:
  • 1 shows an inventive vessel of a tiltable arc furnace in axial section,
  • FIG. 2 shows a top view of the furnace according to FIG. 1.

Wie die Figuren 1 und 2 zeigen, besitzt das Gefäß die Form eines niedrigen Zylinders, mit einem nach unten gewölbten Boden 3. Den oberen Abschluß des Gefäßes bildet ein heb- und senkbarer Deckel, durch den die Elektroden hindurchgehen. In der Zeichnüng sind der Deckel sowie die Elektroden nicht dargestellt.As FIGS. 1 and 2 show, the vessel has the shape of a low cylinder with a bottom 3 that is curved downwards. The upper end of the vessel is formed by a lid that can be raised and lowered and through which the electrodes pass. The cover and the electrodes are not shown in the drawing.

Im unteren Bereich des Gefäßes ist die Schmelzzone 12 vorgesehen, in der sich während des Ofenbetriebes die Metallschmelze sammelt.In the lower region of the vessel, the melting zone 12 is provided, in which the molten metal collects during furnace operation.

In den Figuren 1 und 2 sind zwei Ausführungsbeispiele des Gefäßes dargestellt, u.z. in der linken Hälfte ein Gefäß, dessen Wandung 4 bis nach oben ausgemauert ist, während in der in der rechten Hälfte der Zeichnung dargestellten Ausführung die feuerfeste Zustellung 1 des Ofenherdes nur wenig über den Schmelzspiegel hinausreicht. Der darüber anschließende Teil der Ofenwandung besteht aus zu der Schmelzzone 12 hin offenliegenden, von Kühlmittel durchströmten Kühlelementen (Rohrbündeln) 7. Die Kühlelemente 7 sind an einen nicht dargstellten Kreislauf angeschlossen.In the figures 1 and 2, two embodiments of the vessel are shown, u.z. in the left half of a vessel, the wall 4 is bricked up to the top, while in the embodiment shown in the right half of the drawing, the refractory delivery 1 of the oven range extends only slightly beyond the melting level. The part of the furnace wall adjoining it consists of cooling elements (tube bundles) 7 which are exposed to the melting zone 12 and through which coolant flows. The cooling elements 7 are connected to a circuit (not shown).

Der Bodenbereich des Gefäßes 3 ist mit einer Tragkonstruktion 2 versehen. Die Konstruktion 2 weist über den Umfang des Gefäßes verteilte, vertikal angeordnete Träger 2a auf, die mit einem waagerecht angeordneten, ringförmigen Gurt 2b verbunden sind. An diesem Gurt sind parallel zur Gefäß-Drehachse verlaufende Träger 8a - 8h angeschlossen, die den über den Querschnitt des Gefäßes ragenden Gefäßrand 5 abstützen. Diese Abstützung ist sehr wichtig, denn beim Ofenbetrieb trägt der Gefäßrand 5 das ganze Gewicht des Ofendeckels.The bottom area of the vessel 3 is provided with a supporting structure 2. The structure 2 has vertically arranged supports 2a distributed over the circumference of the vessel, which are connected to a horizontally arranged, ring-shaped belt 2b. Connected to this belt are carriers 8a-8h which run parallel to the axis of rotation of the vessel and which support the edge 5 of the vessel which projects beyond the cross section of the vessel. This support is very important, because when the furnace is in operation, the rim 5 of the vessel bears the entire weight of the furnace lid.

Um - wie bereits geschildert - den seitlichen Zugang bzw. die Manipulation an der Gefäßwand von außen zu erleichtern, sind die Träger 8a - 8h seitlich entfernbar. Wie aus Fig. 1 ersichtlich ist, ist der Träger 8 an seinem unteren Ende bei 10 am Gurt 2b verschwenkbar gelagert. Dazu ist am Gurt 2b ein Lager vorgesehen. Die Schwenkachse 10 verläuft tangential zur Gefäßwandung 4.In order - as already described - to facilitate lateral access or manipulation of the vessel wall from the outside, the carriers 8a-8h can be removed laterally. As can be seen from Fig. 1, the carrier 8 is pivotally mounted at its lower end at 10 on the belt 2b. For this purpose, a bearing is provided on the belt 2b. The pivot axis 10 extends tangentially to the vessel wall 4.

Das obere Ende des Trägers 8b ist über einen lagegesicherten Keil 11 an der Unterseite des Gefäßrandes 5 angeschlossen.The upper end of the carrier 8b is connected to the underside of the vessel rim 5 via a position-secured wedge 11.

Soll zum Beispiel ein Kühlelement (Kühlrohrbündel) 7 repariert oder ausgetauscht werden, wird die Keilverbindung bei 11 gelöst und der Träger 8b von der Gefäßwandung 4 weggeschwenkt. Damit ist die Gefäßwand für die Bedienung von außen zugänglich.For example, if a cooling element (cooling tube bundle) 7 is to be repaired or replaced, the wedge connection is released at 11 and the carrier 8b is pivoted away from the vessel wall 4. This means that the vessel wall is accessible for operation from the outside.

Der Träger 8g ist an seinem unteren sowie oberen Ende über Keile 11 an dem Gurt 2b und dem Gefäßrand 5 angeschlossen. Nach Lösung der Keilverbindungen kann der Träger 8g seitlich abgenommen werden, wodurch die Ausmauerung 1 von außen zugänglich sein wird. Die Reparaturarbeiten an der Ausmauerung können dann von außen her unternommen werden.The carrier 8g is connected at its lower and upper end via wedges 11 to the belt 2b and the edge 5 of the vessel. After the wedge connections have been released, the carrier 8g can be removed laterally, as a result of which the lining 1 will be accessible from the outside. The repair work on the lining can then be carried out from the outside.

Wie Fig. 2 zeigt, sind in zweckmäßig ausgelegten Abständen vier feststehende Träger 9 vorgesehen,, die zum Ausgleich der Spannungen in der Tragkonstruktion dienen. Zu dem gleichen Zwecke sind bei den Ausführungen mit ausgemauerten Gefäßwänden zwischen den Trägern 8a und-der ausgemauerten Wand lose Mantelbleche 13 eingelegt.As shown in FIG. 2, four fixed supports 9 are provided at appropriately designed intervals, which serve to compensate for the stresses in the supporting structure. For the same purpose, loose cladding sheets 13 are inserted between the supports 8a and the bricked-in wall in the designs with bricked-up vessel walls.
